javax.portlet.PortletException: Request processing failed javax.portlet.Por

[Traolly Xiong, modificado 9 Anos atrás.]

Hello ,
I seem to get a portlet exception error on our DEV environment but not on my local LR instance.

Error:

Any ideas why this would happen?

Thanks.

If you drill down in stacktrace there is an NPE.

Caused by: java.lang.NullPointerException
at com.gsa.portal.portlet.controller.GSASearchController.homeGSASearch(GSASearchController.java:114)

I think issue is because of this exception, try fixing it first.

Typically the :

<requires-namespaced-parameters>false</requires-namespaced-parameters>

tag in the "liferay-portlet.xml" resolves the issue in 6.2, but the spring portlet "@RenderMapping" method is returning the error....

Quite tricky.... I'll continue to look at the NPE error but if you have any other slick ideas.. let me know..

Much thanks!

I tracked the NPE caused by the code below:

ThemeDisplay themeDisplay = (ThemeDisplay) request
.getAttribute(WebKeys.THEME_DISPLAY);
String userName = themeDisplay.getUser().getScreenName();

The post below says the plugin needs to be built again with a 6.2 sdk, which I've done already...

https://www.liferay.com/community/forums/-/message_boards/message/33525124

Tricky one. There must be something missing...

[Traolly Xiong, modificado 9 Anos atrás.]

New check out with different ant / java versions build, built war, and deployed did not cause any more NPE issues.

Thanks.
